The hub "is provided with .a pin member 14 whichmay belpressed into .a recess l5 Jextending aroundlthe periphery of thestandard "whenx'the *sleeveiswaised, to retain the sleeve xincitszraised:position. The standard maybe protvided with a plurality of suchrecesses spaced :glonglthetstandard, whereby the sleeve may be*retain'edgin several positions on the standard.

. The.zpackage-supporting plate is provided with "depending guide means22 "extending through guide holesfz3 in the sleeve-like member "whichpermit the sleeve-like member to be moved in an axial directlonielativeto the :plate and the sleeve and {.the!- plate to lie-rotated together.'Cover=manipulating members II are carried by the sleeve. and areadapted to bemoved radially :inwardlyand outwardly in the radiallyextending slots 1 8 in the brackets l9 attached to the bottom of thesleeve. The-slots in the bracketsare in line with the slots in thepackagesupporting plate. "The cover-manipulating vmeansextend upwardlythrough the depending portions of the gripping members and the upperportions of the cover-manipulating means are bent over to form aninverted U-shape as shown by reference character 20. Thepackage-contacting surfaces of the gripping members are recessed toaccommodate the cover-manipulating means when the sleeve is in its lowerposition.

Instead of having the sleeve-like member movable in an axial directionrelative to the packagesupporting plate, as described above, thesleevelike member may be attached to a base; and the standard,supporting the package-gripping members and the package-supporting andscroll plates, may be arranged so as to be axially movable and rotatablerelative to the sleeve-like member. As in the embodiment of Figure l,the package-supporting plate is supported for axial movement relative tothe sleeve-like member and such movement is assured by the rods 22secured to the plate and extending through apertures 23 in thesleeve-like member. This is illustrated in the embodiment of Figure 8 inwhich the huh I: is fixed in a supporting bracket 25a and the shaft la(replacing the standard I of the embodiment of Figures 1 to 3) isrotatably and axially slidable with respect to the shell ll. Shaft la isprovided with an additional groove or notch 26 to receive detent [4 whenthe shaft is raised, groove l5 serving when the shaft is lowered. Thelower end of the shaft may be provided with a hand lever 21 tofacilitate manipulation thereof. The operation is similar to that ofFigures 1 to 3 as hereinafter described, but instead of manipulating thesleeve Ila, the lever 21 on the shaft la is manipulated to effect therelative movements needed.

In accordance with the preferred practice 0 the invention; an endportion'25a of a tubular fabric cover member, such as shown in thepatent to Pedlow 2,230,067, is drawn over the grippin members and thesleeve, when they cre m the lower position shown in Figures 1, 2 and 3of the drawing. The other end portion 26a of the cover member is thenplaced over the tops of the gripping members and cover manipulatingmembers and is inserted or tucked in a gathered condition' in the spaceformed between the gripping members above the center of thepackage-supporting plate. An annular yarn or thread package I6 is placedonthe package-supporting plate over the gripping members and the covermember, as shown in Figure 4. The sleeve and the package-supportingplate are rotated relative to the standard and the scroll plate to movethe gripping members outwardly to engage and firmly grip the package andalso to center the package on the package-supporting plate; The sleevemember is then raised, which uniformly applies the end portion of thecover member engaging the sleeve to the outer side of the package, as

shown in Figure 5. At the same time the covermanipulating members areraised, extending the other end portion of the cover member upwardly, asshown in Figure 5, where it is in position to be readily engaged by anoperator. The sleeve member is retained in the upper position by the pinin the hub member which is pressed into the recess in the standard. Theupper end of the cover is then folded down over the sleeve memher, asshown in Figure 6. The pin member is withdrawn from the recess in thestandard and the sleeve is lowered, causing the portion of the covermember engaging the sleeve to be uniformin overlapping relation to theother portion of the cover member pplied to the outer side of thepackage, as shown in Figure 7.

The apparatus as shown in Figures 9 to 12 of the drawings comprises aplurality ofyarn or thread package-supporting units mounted on aconveyor and moved to various positions in which they receive protectivecovering means, then packages, then the covers are wrapped about thepackages, and the wrapped packages are removed.

In this embodiment, reference character A indicates generally one of aplurality of units for engaging and supporting a yarn or thread package.The unit comprises a pot-shaped receptacle or member 32 comprising aflat bottom, an upright cylindrical or sleeve-like member or side wall,and an axially extending hub member 33 having an axial bore. The sleeveis fixed'to a plate 34 which is attached to the links 35 of a conveyorchain. The conveyor moves in a closed path and passes over andis drivenby the sprocket wheels 36. Means which are not shown are provided fordriving the sprocket wheels. A circular package-supporting plate 31, Ofslightly less diameter than the inside diameter of the sleeve-likemember, is centrally and rotatably mounted on the end of the shaft 38which extends through 'the'sleeve-like member and the axial bore in thehub member and carries fixedly secured thereto a facing plate 31a uponwhich the yarn or thread package actually rests. The shaft is adapted tobe rotated and moved axially in the bore in the hub member. Thepackagesupporting plate is provided with a plurality of radiallyextending slots 3911. A scroll plate 40 is fixed to the end of the shaftbeneath the package-supporting plate and is provided with a pinrality ofscroll-like or spirally extending slots M. A roller or cam follower 42is fixed to the end of the shaft. Also a pair of substantiallydiametrically opposed outwardly extending arms 43 and 44 are fixed tothe shaft above the roller. A plurality of substantially L-shapedpackagegripping members 45 arranged for axial sliding motion withinslots or guideways 39 formed in the facing plate 31a and havingdepending portions 48 aremounted on the package-supportingplate with thedepending portions passing through the slots in'the package-supportingplate and the scroll plate. The scroll plate is urged to rotate relativeto the package-supporting plate by the spring means 41 attached at oneend to a pin secured to the package-supporting plate and at the otherend to a pin secured to the scroll plate. The spring is provided with aU- shaped member 48 intermediate its ends which straddles the shaft topermit the direction in which the spring exerts its force to pass from aposition on one side of the shaft to a position on the other side. Thespring may rotate the scroll plate relative to the package-supportingplate in either direction depending upon which side of the shaft thedirection of force of the spring extends. The package-supporting plateis provided with depending guide means 49 extending through guide holes50 in the bottom of the sleeve-like member which permit axial movementbut not rotary movement of the packagesupporting plate relative to thesleeve-like member. A track 5! on which the roller 42 is adapted to rollis positioned below and extends in the direction of travel of theconveyor. The track is provided with a drop or lower section 52 which ly applied to the outer side of the packagean'd lowers thepackage-supporting plate during a portion 01 the movement of thepackage-supporting unit through the apparatus. Cam or deflecting members53 and 54 are positioned aboveand on opposite sides of the track in thepath of the outwardly extending arms 43 and 44 mounted on the shaft. forrendering the unit inoperative comprising the annular plate memberrotatably supported on the bottom of the sleeve-like member. The annularplate is provided with handle means H, whereby it may be rotatedrelative to the sleevelike member about its axis. Guide holes 13 areformed in the annular plate which are' of the same size as the guideholes 50 in the bottom of the sleeve-like member and are positioned sothat they may be aligned with the guide holes in the sleeve-like member.

In accordance with a preferred practice of this embodiment of theinvention, end portions of tubular fabric cover members such as of thetype Means are provided shown in the patent to Pedlow, 2,230,067 aredrawn over the'gripping members 45 and the sleeves 32 of thepackage-supporting units when they are in the upper position at theloading end of the machine as shown in Figures 9 and 10. The uppermostend portions of the cover-members are then placed over the tops of thegripping members and are inserted or tucked in a gathered condition intothe cup-like hollow space formed I between the gripping members 45 abovethe center of the package-supporting units. yarn or thread packages arethen placed on the package-supporting units over the gripping mem bers45 and the cover members applied thereto. As the package-supportingunits move along with the conveyor the arm 43 on the shaft 38 strikesthe cam or deflecting member 53. This rotates the shaft 38 in aclockwise direction as shown in Figure 11. The rotation of the shaft andthe scroll plate in a clockwise direction as shown in Figure 11 urgesthe package-gripping members outwardly. With this motion, the directionin which the spring extends is moved to the other side of the shaft..The spring thereby continues to urge the scroll plate and shaft in aclockwise.

direction and the gripping members radially outward. This operationcenters the package on the package-supporting unit and retains it inposition. The free end of the cover member is then withdrawn from thespac formed within the upper portions of the gripping members 45 at thecenter of the package supporting unit and is placed over the outside ofthe upper portion of the package. .As the package-supporting unit passesover the drop or lower portion 52 of the Annular track section, theroller 42 rolling on the track permits the shaft 38 andpackage-supporting plate package-supporting unit has passed over thedrop or lower portion of the track, the package-supporting unit passesby the deflecting member 54 which is positioned on the side of the trackopposite to the side on which the deflecting member 53 is positioned.The outwardly extending arm 44 fixed to the shaft 38 of thepackage-supporting unit strikes the deflecting member 54 causing theshaft and the scroll plate to be rotated in a counterclockwisedirection, as shown in Figure 11.

The rotation of the scroll plate in a counterclock wise directionretracts the gripping members moving them radially inward. As thedirection in which the spring member extends passes to the other side ofthe shaft, the spring member urges the scroll plate to continue torotate in a counterclockwise direction which retains the grippingmembers in retracted position. The wrapped package may then be readilyremoved from the package-supporting unit by hand. If for any reason itis desired not to complete the application of the covering means to acertain package, the covering applying means for the unit supportingthis package may be made inoperative. This is accomplished by rotatingthe plate 10 attached to this unit so that the holes 13 are out ofalignment with the depending guide members 49. The plate member. in thisposition prevents the package-supporting plate from moving in an axialdirection relative to the -sleeve.member as the unit passes over thedrop or lower portion of the track.

Itis readily seen that with this invention the cover is uniformly andevenly placed on the package without rubbing the cover across thepackage and damaging the thread or yarn.
